Gas Calibration

Calibration Gas is a reference gas or a gas mixture that is used in the calibration of analytical instruments like gas detectors and analyzers. To be a calibration gas, the gases must meet international standards. The gas must be traceable as per the standards and along with this PTL (Preparation Tolerance Level) and CA (Certification/Analytical Accuracy) are also must in providing a right calibration gas mixture.

Generally it is a mixture of two or more gases blended together with a carrier gas that can be used further as a reference gas in research centers or laboratories in gas analyzers and gas detectors. Accuracy is must in all aspects that are must for any calibration gas mixtures. Thus a calibration gas must be of precisely defined nature and composition like Zero gas.


Hema Gases is a renowned manufacturer, supplier and exporter of Calibration gases in India meeting national and international standards. Calibration gas mixtures are supplied to industries via carbon alloy steel or aluminum cylinders.  We provide highly accurate calibration gas with specified tolerance and these are prepared using highly accurate weight measuring instruments for better accuracy.
